Radiation Physics and Equipment


Course Features

Course Details


The aim of this module is to provide a learning resource for all dental team members involved with radiology.

Successful completion of this course fulfils GDC and CQC requirements for the Ionising Radiation (Medical Exposure) Regulations (IRMER) 2000 and IRR99 for continuing education in radiation physics and equipment.

This module covers IRMER requirements for, radiation physics and equipment the production of x-rays, their properties and interactions which result in the formation of a radiographic image, and the biological effects of radiation and its risks and benefits.

Radiography and Radiation Protection is a GDC recommended subject for continuing professional development.

This is the first module in a series of four modules.

The GDC requires dental professionals to link their CPD activities to at least one development outcome as part of the new enhanced CPD scheme.

This module can be linked to development outcome C: Maintenance and development of knowledge and skill within your field of practice.

Suitable CPD for all dental team members involved with radiography.

Completion of this module and passing the associated quiz will satisfy GDC requirements for 2 hours of CPD in Radiography and Radiation Protection.

It meets IRMER requirements for learning relating to radiation physics and equipment.

The content does not have to be completed all at once, you will be returned to where you left off when your restart the e-learning module.

Topic 1:  Introduction

Topic 2:  The principles of radiation physics

Topic 3:  The radiobiological effects of x-rays

Topic 4:  Radiation doses and risk

Topic 5:  Radiographic equipment

Topic 6:  Summary

On completion of this module you should be able to:

  • Define ionising radiation and explain the general properties of radiation.
  • Describe the production of x-rays as well as the biological effects, risks and benefits.
  • Define the terms exposure, effective dose, absorbed, equivalent and collective dose.
  • Explain the stochastic, somatic and deterministic effects of radiation and give examples.

There are interactive questions and activities throughout the module which are not assessed.

On completion of the module there is a separately assessed quiz.

You will need to achieve 70 % for this quiz to complete the module and access your CPD certificate. You will have two opportunities to achieve the required score.
